• Blue: utility air up to 300 psi.
• White: breathing air up to 300 psi.
• Yellow: breathing air 301 psi to 3,000
• Red: breathing air more than 3,000 psi.
Prior to delivery, the installer must test
and certify the air system. If the system
is for breathing air, a sample must be
drawn and tested to ensure that the
breathing air meets the air quality standards described in NFPA 1989, Standard
on Breathing Air Quality for Emergency
Services Respiratory Protection.
Chapter 25, Winches
There are only a few requirements
for winches used on fire apparatus. The
winch needs to be installed in accordance with the winch manufacturer’s
recommendations, the wire or synthetic
rope must be a minimum of 75 feet, and
the winch must have a clutch assembly
to allow free spooling.
Electrically powered winches can
either be permanently installed or
removable by use of a receiver system.
The fixed units are usually at the front or
rear of a rescue unit. Typically, the fixed
electrical winches have higher capacities
than the removable type.
Removable winches plug into receivers
that can be mounted on any location on
the apparatus. A quick disconnect power
receptacle sized for use with the winch
provides electrical power.
Hydraulically driven winches are the
more heavy-duty, permanently mounted type with a hydraulic reservoir and
winch engagement controls in the cab. A
“Hydraulic Winch Engaged” indicator is
required in the cab.
For all types of winches, the winch
control must be a minimum of 12 feet
from the actual unit to prevent injury in
case the cable snaps.
Chapter 26, Trailers
For the purpose of the standard,
trailers transporting equipment or other
vehicles under emergency response
conditions are considered fire apparatus.
Trailers are classified as follows:
• Type I—requires attachment to prime
mover to operate and for electrical
power on scene.
• Type II—disconnects and operates at
• Type III—“low-boy” open trailer types
for moving heavy equipment.
Trailers with a 3,000-pound GVWR
are required to have a braking system.
Safety chains and wheel chocks must
be provided. If the trailer is a Type I
or Type II, warning lights that comply
with Chapter 13 are required. Type III
trailers require only lower zone warning lights. Type I and II trailers are
required to be equipped with ground
lights. Trailer work surfaces, steps, and
walkways are to have surface lighting.
Reflective marking that complies with
Chapter 15 is to be provided on Type I
and II trailers.
Chapter 27, (Reserved)
Chapter 28, Ultra-High-Pressure Fire Pumps and
The ultra-high-pressure chapter is
new in this edition of the standard and
pertains to fire pumps with a minimum rated capacity of six gpm and a
rated discharge pressure of 1,100 psi
or greater while taking water from the
apparatus water tank. The purchaser
can specify other flows depending on
the requirements. Many of the requirements in this chapter are the same as
for other pumps.
From this article, you can see that there
are many decisions to make when specifying apparatus. Preparing specifications
and purchasing fire apparatus are major
responsibilities that represent a sizable,
long-term investment of community funds.
Approach this complex project in an orderly fashion. Making intelligent decisions
based on investigation, research, and
evaluation of available products will result
in a finished product that will serve your
community long into the future.
